I had a similar experience growing up. My lab I had as a child would tree coon and feral cat, and even a bobcat, along the river bottoms where I grew up. Day or night, summer or winter, his nose and his instinct to pursue and tree game were amazing.
My hound hunting friends always thought I was lying until they saw him tree a feral cat one day in July in the middle of a starthistle patch; they wanted to breed their Walkers to him after that!
Count yourself fortunate to have such a unique dog.
